So at 4PM today, I received an email from Blogger saying that one of my sites has been deleted. As was explained, this is the result of their "automated classification system marking it as spam." Of course, it's not a spam blog, so they are giving me a chance for an "unlock request."
I'm not worried yet. I experienced this before, and after a few hours, my site was back on. Here are some screenshots for your reference.
Simply fill out the required fields.

When done, click on the "Send request" button, and this box will appear.
